Background
- Possible reversible cause of dementia
- CSF buildup in the ventricles leading to increased intracranial pressure with edema of the periventricular white matter and corona radiata
- Sacral motor nerve fibers that produce gait instability; incontinence ensues when compressed
==Clinical Features==
- Gait disturbance is most common
- Memory loss and dementia symptoms may be mild, subtle
- Incontinence is usually later stage, though sensation of urinary urgency is usually present before incontinence
Differential Diagnosis
- Alzheimers
- Stroke
- Parkinson's Disease
- Electrolyte abnormality
- Malignancy
- Uremic encephalopathy
- Hydrocephalus ex vacuo (diffuse cerebral atrophy on CT)
Evaluation
Management
Disposition
- Workup typically is extensive and performed as an outpatient.
- Refer to neurosurgery
